No. The acronyms stand for different, non-overlapping frequency ranges. Since
the #1 immutable requirement for radios to be able to talk to each other is that
they be on the same frequency, and since HF, UHF, and VHF radios are by definition
on different frequencies, that match would be harder to operate successfully than
a mixed marriage.
Not a whole lot other than use it for a paperweight. Best thing to do is sell it unless you can find a reason to keep it.
Not really. The UHF operate on an entirely different frequency spectrum that the VHF. UHF ranges from 225-399.975 whereas the VHF ranges from 108-115.975/116-148.975/ or 30-89.975

Most planes have VHF radios. Military planes have UHF radios, and some planes have satellite communications.

Generally speaking, VHF or UHF radio. VHF is also used to communicate with ground personnel (heli logging, SAR, firefighting, etc). The 'system' consists of a radio, antenna cable, and external antenna. an intermediate antenna switch can be used to allow multiple radios of the same band to use the same external antenna.
If you live in a very populated area, uhf radios will be able to pick up signals without interfering with your other wireless devices. For a less populated area, vhf is the more sensible choice.

it rely depends where you are. UHF stands for ultra high frequency and vhf stands for very high frequency. vhf has ben around longer than UHF making them cheaper to use but UHF means smaller antennas and better output. vhf is better in rural locations with expectations to be used in close proximity because buildings and natural barriers affect them. UHF can easily get through buildings and natural barriers but you pay lots more for them. but any to answer you question they do use both just ask your locals what they use.

Whether its a handheld, a mobile in a car, or a base unit, they all work the same way. They work just like your cheap walkie-talkies from Wal-Mart that you played with as a kid, you key the radio and speak and the others hear you. As far as vhf or uhf, these are bands that the radios transmit on. The typical business/industrial/public safety bands are 800 mHz, VHF, and UHF. VHF stands for Very High Frequency and are from 30 to 300 mHz but typically for these radios it will be in the 136 to 170 mHz range. UHF stands for Ultra High Frequency and run from 450 to 470 mHz. And there are lots of areas in between that are used by amateur radio operators. VHF is good for long range on flat terrain. For example on the Interstate. Not so good for urban type areas with lots of buildings, concrete or steel. UHF is good for urban type areas where you may be in a building. Not as good for long range compared to VHF, but is better than VHF in urban settings as it can penetrate steel and concrete better. So it really depends on how you will use your radios as to which band you will want to consider. As a side note to this there are a few frequencies that the FCC has set aside for say business use but they are limited to certain handhelds with certain power requirements, these are GMRS (UHF) and MURS (VHF). You cannot use mobiles or bases on most of these. To be able to do this you must apply for and be granted a license from the FCC. IF in doubt on whether or not you need a license check out www.fcc.gov for info.

By using a VHF radio.
Very High Frequency and Ultra High Frequency. They are ranges of frequencies of radio waves in the electromagnetic spectrum. VHF ranges from about 30MHz to 300MHz, UHF is from about 300MHz to 3GHz. They are further subdivided into bands for; marine, amature, and other 2 way radio use, also designated channels for television and radio broadcast stations, as well as other uses throughout the world. In the US on the now defunkt analog television system VHF channels were 2-13 UHF channels were 14-83.
They communicate by two-way VHF radio.
